THREE NEW COLEOPTERA FROM WASHINGTON STATE. 



By H, C. Fall, Pasadena, Cal. 



Bembidiurti pugetanum n. sp. Form nearly as in lorquini, or the Euro- 

 pean Utorale, viridiseneous, surface alutaceous, palpi and antennae dark 

 metallic, the latter with basal joint pale beneath, femora at base and tibise 

 beneath pale. 



■ Mentum tooth triangular. Prothorax one half wider than long, very 

 slightly wider at base than at apex, sides moderately rounded in front and 

 sinuate behind, narrowly margined; hincf angles rectangular and a little 

 prominent; disk evenly alutaceo-reticulate, with feeble traces of trans- 

 verse wrinkles, hind angles with a short oblique carina ; submedian margi- 

 nal seta present. Elytra fully one half wider than the prothorax, striae 

 moderately punctate, the fourth not distinctly sinuate, intervals 2-4 with 

 purpHsh black stripe, more extended on the third — on which are the 

 usual two squarish impressions. Body beneath greenish black, shining. 



Length 6 mm.; width 2.45 mm. (type c?). 



Described from two examples (c? ?) taken at Seattle, Washington, by 

 Prof. O. B. Johnson. 



This species, by the form of the mentum tooth, the presence of 

 the median marginal seta of the prothorax, and the carinate hind 

 angles of the latter, would in my table* be placed near cannula, 

 which however it does not very much resemble. In cannula the 

 prothorax is more strongly transverse, the surface lustre more 

 or less cupreous. 



Cafius johnsoni n. sp. Black, the inflexed margins of the elytra, legs, 

 and ventral segments sometimes more or less brownish. Antennae black, 

 not reaching the middle of the prothorax, joints 5-10, gradually becoming 

 a little wider than long. Head — exclusive of mandibles — squarish, often 

 larger in the male, strongly shining, with a minute wavy strigillation which 

 disappears at the middle of the disk, an externally arcuate series of three 

 large punctures on each side of the disk, and two or three others at the 

 hind angles. Prothorax subequal in width to the head, slightly longer 

 than wide, sides parallel, surface throughout polished, each side of the 

 middle a series of four punctures, the posterior one more distant, with a 

 few similar coarse punctures anteriorly toward the sides. Elytra a little 

 longer than the prothorax, evenly, closely, rather coarsely punctate ; pu- 

 bescence thin, dusky, inclined, and with several series of widely spaced 

 longer erect setae. Abdomen similarly thinly pubescent, the hairs more 

 recumbent, punctuation finer than on the elytra; beneath more coarsely
